FYI.. in case anyone finds this post in the future. I have not found any solution to make this work on the latest versions of 6.5 or 6.7. The only solutions I have found were rolling back to 6.0 (with all latest patches as of this writing is fine) or 6.5 build 10719125. Something in 6.5 build 10884925 is what's breaking it for me. If you install a fresh 6.5 U2 you can create a custom baseline that only includes updates before 11/27/2018 (11/26 or earlier). That will take you up to build 10719125.
We experienced the same issue with ESXi 6.7 and quad port cards:
|Device name:||82576 Gigabit Network Connection|
VMware informed us that the support for this card was dropped in ESXi 6.7:
As we have just a few of these cards we decided to replace them.
